I also included the facebook social comments plugin widget on my web page.
Is it possible to post a comment on to the web page, using Graph api of facebook ?

The user will be logged into my web application using facebook, and then he must be able to post facebook comment on the web page in my application, through API. So the widget will be displaying all the comments that are posted directly on the page, and those that are posted through API.

I am not sure what to be used for the post_id. Is it the url of my webpage, that has the facebook comments widget?

postId = the Id of the post where the comments belongs to. Without the API does not know where to put to comment to. Is the widget from Facebook? Is it iFrame based or Javascript? Did you write it on your own?

The widget is not from facebook. I have manually included the widget on my page, using an iframe code.

How do you get the comments? Loaded via API? Can you provide some code here? I mean to show up comments you also need postIds? Without more information about the widget and the code inside it is hard to help.

Ok, i am actually not displaying comments from facebook post on my page. I have just setup a comments widget on my pages by specifying a unique url for each page. But i understand now that it is not possible to add comments via API on to my web page. Thanks for your suggestion.
